'To all whom it 'may concern:

. Be it known that I, ROLLEN OTTO NEWPORT, a citizen of the United States, residing at Garden City, in the county of Finney and State of Kansas, have invented a 5 new and useful SpringWheel, of which the following is a specification.

This invention relates to carriage Wheels, more particularly to wheels in which spring spokes are utilized to provide resiliency therein; and has for its object the `provision of a wheel of the character described that is imple, strong and durable in construction, that may be taken apart and repaired at little cost, and that may be sed upon any ordinary axle. 4The "invention consists in the novel construction, A combination and arrangement of parts hereinafter fully escribed, claimed, and illustrated in the accompany- Ag' drawings, in which,- Y Vlfigure l is a side elevation of a Wheel constructed in accordance with this invention; Fig. 2 is a central lon- 2 gitudinal section through the hub of the wheel. Fig. 3 is a central transverse section of the hub, and Fig. 4 is a transverse sectional view of the rim.

` JReferring to the drawings, the hub l is constructed of metal and has a central annular collar 2 formed integral therewith, having outwardly-converging sides and provided with tangential slots 3 adapted to receive the inner ends of the spokes. The ends of said hub are Screw-threaded externally and provided with corref ndingly threaded nuts 4. Between the nuts and the llar are washers 5 having cuppedA inner faces con Hiring to the converging adjoining sides of the collar. .The spokes 6 are made preferably of spring steel, and

have laterallycxtending oppositely-disposed-wings or. .1. lugs 7 upon the inner ends thereof adaptedto fill the cupped Washers and nuts embracing said collar, the-.. d I lugs 7 being of slightly greater Width than the collar in` order to insure positive contact between themiandthe washers. The spokes are sprung into symmetrical slots in. the hub collar andl to be held in place by the curves and their outer ends are securedto the rim of the wheel by riveting or other suitable means.

In the construction illustrated, the rim is of G shape in cross section, as indicated in Fig. 4, and a thin annu-'74 lar metallic spokesecuring band 8 coversthe open inner side of the rim and has the extremities of the spokes attached thereto bg rivets or similar fastening devices, l

the heads of which are disposed Within the space between the opposed edges of the rim to hold'the band in n a position. I i

Having thus fully described the invention, what is In a wheel, the combination of a hub having threaded 5o claimed and desired to be secured by Letters Patent is2- i opposite ends and a Vcentral annular collar having down' warmly-converging sides and tangential slots, curved .sp1-ing spokes having lateral extensions at their inner ends of slightly greater Width than the collar and disposedwithin the slots, cupped washers to engage the spoke end V extensions, and nuts to secure the washers in place.
